Fried-Krupp Nirosta drilling barrels

[Raybenedetto]

I have a 1925 JP Sauer sidelock drilling serial #280107 with Fried-Krupp Nirosta steel barrels that are in the white. Can anyone refer me to a gunsmith that can re-blue the barrels to original condition. Barrels are soft soldered, so stainless hot blue is not an option. Thanks, Ray

Ray,
You might try any of the gunsmiths that are in the trade directory in Waidmannsheil.

Guns with Nirosta or Antinit barrels without any blueing. Sometimes I saw drillings and combination guns with shot tubes and ribs perfectly black, but the rifle barrel white. Reason: blueing is a rusting process. Now, get stainless steel to rust! Even if you succeed by using all sorts of tricks, the resulting black Oxyde layer will soon wear off again.

Ray,

It may be a long shot on your gun but I have used a product called Stainless Black 370 to darken non-gun stainless parts with fairly good results. It's available from Caswell Plaiting their number is 855-CASWELL. I would try it on a hidden spot first and it is very acidic. This is the only thing I know that might work. There were a couple of gunshops out there that blackened stainless but I don't have that information any longer and I think they used a hot salt solution that will not work for you. Good luck,

Diz

If I might ask, why blue them at all?

Thanks Alex, I have learned that the barrels were most likely iron plated , then rust blued. I'm trying now to find someone who does iron plating, without success.

Thanks Diz, I'll give them a call

[Raybenedetto]

That's a good question. The original barrels were blued, there is an area of remaining blue under the forend. I'm trying to get the gun back to as original condition as possible. The has had a rough life and deserves better. Ray

Ray, I have had pretty good success blueing Bohler Antinit utilizing the "acid fume" method via a brochure from Brownells. Got it good and dark with about six cycles. It has worn pretty well. Be SURE to plug the bores when you place it in the fume box or you will surely etch them. Cannot promise anything on your tubes as they may be different metallurgically. steve

Thanks Steve, will check it out.
